Halation looks

Highlights

  • Flow: silk, light bands, mesh gradients, ribbons, lit shapes, a real-time fluid simulation you paint with the mouse, or any image you drop in.
  • Glass: nine physically based glass types (reeded, wavy, rings, glass-block tiles, hammered, water, crystal, rain and pyramids) with adjustable index of refraction, frost, streaks, dispersion, caustics, Fresnel reflections, tint, partial panes and a second stacked pane.
  • Screen: halftone, line screens, LED matrix, CRT, mosaic, topographic contours and dither.
  • Color and finish: an OKLab gradient editor with a palette library and generator, relief and gloss lighting, film grain, bloom, vignette and chromatic aberration.
  • Export: 8- and 16-bit PNG, JPEG and WebP at up to 4× any canvas size, copy to clipboard, burst capture as a .zip, and seamless-loop video.
  • Workflow: 20 built-in looks, settings search (press /), saved looks with import and export, share links, undo/redo and Surprise me.
  • Performance modes (Auto, Eco, Balanced, Max) keep the preview smooth on modest hardware. Exports always render at full quality.
